Abstract
The utility model relates to a temperature controlled multifunction electric rice cooker with intermitting heating function, a timer with intermittent energizing contacts and a normal energizing contact and a thermosensitive element K3 are arranged on the base of an electric cooker which comprises a cooker body, a heating element RR, a magnetic steel temperature limiter K1 and a thermophore K2, the intermittent energizing contact 2 and 3 of the timer are connected with the thermosensitive element K3 in parallel, and then are connected in series with a parallel loop composed of the magnetic steel temperature limiter K1 and the thermophore K2 and the heating element RR. The utility model has the advantages of simple structure, low cost, easy use, decoction non-overflow and distinct energy-saving effect and has the functions of automatic cooking and intermitting heating.
Description
The utility model relates to a kind of intermittently temperature control multifunctional electric rice cooker of heating function that has.
Can not only cook for making electric cooker, can also realize cooking congee, stew soup, boiling water, and can not increase too much cost, (patent No. is: 93224610.9) to have introduced a kind of electric cooker that adopts temperature control pause switch circuit on patent gazette, its advantage is to satisfy above-mentioned requirements, yet the cost of the temperature control pause switch circuit that adopts is also higher.
The purpose of this utility model is the existing capability by timer, provides more simple, cost temperature control multifunctional electric rice cooker still less.
The technical solution of the utility model so realizes, set up a timer and a temperature-sensitive element that has intermittently power-on contact and normal open contact on an electric cooker that includes pot body, heater element, magnetic steel temperature limiter and warmer, the intermittently power-on contact of timer and temperature-sensitive element are also disliked the back and are drunk parallel circuit and the heater element that temperature limiter and warmer form by magnetic and be in series.
The utility model embodiment is described further in conjunction with the accompanying drawings.
Accompanying drawing is the utility model circuit theory diagrams.
Shown in figure, K1 is a magnetic steel temperature limiter, K2 is that warmer, RR are heater element, the timer of setting up has intermittently power-on contact and normal open contact, and 2,3 backs in parallel, intermittently power-on contact of temperature-sensitive element K3 and timer are in series with parallel circuit and the heater element that magnetic steel temperature limiter R1 and warmer K2 form.When cooking, 1,4 contactings, K1 closes, at this moment, heater element RR heating is when arriving 103 ℃, K1 disconnects, then, when cooking congee, set the regularly shut-in time by warmer K2 insulation, K1 closes this moment, contact 1,2 is connected, by thermoswitch K3, and the RR heating, until 85~98 °, K3 disconnects, and at this moment, 2,3 control heater element RR intermittently heat by the intermittently power-on contact on the timer, make the Shi Buhui that cooks congee produce spillover like this, arrived the turn-off time that timer is set, 1,2 contacts disconnect, the end of cooking congee.The intermittently power-on contact is for intermittently exporting reed, the reed convex platform is by timer travelling gear and cam driven, 3 cycles of contact are swung up and down, contact 2~3 periodically connecting and disconnecting like this, reach the heating of intermittently controlling RR, in order to control the cycle of turn-on time, can by a mechanical device to regulate between the reed distance be contact spacing from.
The utility model control circuit is simple in structure, and cost hangs down to have automatically and boils, and functions such as heating at intermittence are easy to use, congee, the outer benefit of Tang Buhui, and energy-saving effect is obvious, by consumers in general are accepted.
Claims (2)
1, a kind of temperature control multifunctional electric rice cooker that includes stew body, heater element RR, magnetic steel temperature limiter K1 and warmer K2, it is characterized in that, be provided with a timer and a temperature-sensitive element K3 who has intermittently power-on contact and normal open contact, the intermittently power-on contact 2,3 of timer is in series with the parallel circuit and the heater element RR that form with magnetic steel temperature limiter K1 and warmer K2 after temperature-sensitive element K3 is in parallel.
2, temperature control multifunctional electric rice cooker according to claim 1 is characterized in that, described temperature-sensitive element can adopt bimetallic temperature sensitive switch or thermistor or magnetic steel temperature limiter.
